Shubhra reports that their laptop is heating up over s2idle. Even though
it's getting into the deepest state, it appears to be having spurious
wakeup events.
While debugging a tangential issue with the RTC Carsten reports that recent
6.1.y based kernel face a similar problem.
Looking at acpidump and GPIO register comparisons these spurious wakeup
events are from the GPIO associated with the I2C touchpad on both laptops
and occur even when the touchpad is not marked as a wake source by the
kernel.
This means that the boot firmware has programmed these bits and because
Linux didn't touch them lead to spurious wakeup events from that GPIO.
To fix this issue, restore most of the code that previously would clear all
the bits associated with wakeup sources. This will allow the kernel to only
program the wake up sources that are necessary.
This is similar to what was done previously; but only the wake bits are
cleared by default instead of interrupts and wake bits. If any other
problems are reported then it may make sense to clear interrupts again too.

Making virt_to_pfn() a static inline taking a strongly typed
(const void *) makes the contract of a passing a pointer of that
type to the function explicit and exposes any misuse of the
macro virt_to_pfn() acting polymorphic and accepting many types
such as (void *), (unitptr_t) or (unsigned long) as arguments
without warnings.
Also fix all offending call sites to pass a (void *) rather
than an unsigned long. Since virt_to_mfn() is wrapping
virt_to_pfn() this function has become polymorphic as well
so the usage need to be fixed up.

The commit 06470f7468c8 ("mac80211: add API to allow filtering frames in BA sessions")
added reorder_buf_filtered to mark frames filtered by firmware, and it
can only work correctly if hw.max_rx_aggregation_subframes <= 64 since
it stores the bitmap in a u64 variable.
However, new HE or EHT devices can support BlockAck number up to 256 or
1024, and then using a higher subframe index leads UBSAN warning:
UBSAN: shift-out-of-bounds in net/mac80211/rx.c:1129:39
shift exponent 215 is too large for 64-bit type 'long long unsigned int'

This might_sleep() goes back a long time: it was originally introduced
way back when by commit 010060741ad3 ("x86: add might_sleep() to
do_page_fault()"), and made it into the generic VM code when the x86
fault path got re-organized and generalized in commit c2508ec5a58d ("mm:
introduce new 'lock_mm_and_find_vma()' page fault helper").
However, it turns out that the placement of that might_sleep() has
always been rather questionable simply because it's not only a debug
statement to warn about sleeping in contexts that shouldn't sleep (which
was the original reason for adding it), but it also implies a voluntary
scheduling point.
That, in turn, is less than desirable for two reasons:
(a) it ends up being done after we successfully got the mmap_lock, so
just as we got the lock we will now eagerly schedule away and
increase lock contention
and
(b) this is all very possibly part of the "oops, things went horribly
wrong" path and we just haven't figured that out yet
After all, the whole _reason_ for having that get_mmap_lock_carefully()
rather than just doing the obvious mmap_read_lock() is because this code
wants to deal somewhat gracefully with potential kernel wild pointer
bugs.
So then a voluntary scheduling point here is simply not a good idea.
We could certainly turn the 'might_sleep()' into a '__might_sleep()' and
make it be just the debug check that it was originally intended to be.
But even that seems questionable in the wild kernel pointer case - which
again is part of the whole point of this code. The problem wouldn't be
about the _sleeping_ part of the page fault, but about a bad kernel
access. The fact that that bad kernel access might happen in a section
that you shouldn't sleep in is secondary.
So it really ends up being the case that this is simply entirely the
wrong place to do this debug check and related scheduling point at all.
So let's just remove the check entirely. It's been around for over a
decade, it has served its purpose.
The re-schedule will happen at return to user space anyway for the
normal case, and the warning - if we even need it - might be better off
done as a special case for "page fault from kernel mode" once we've
dealt with any potential kernel oopses where the oops is the relevant
thing, not some artificial "scheduling while atomic" test.

The source for Rust's 'core' library is needed to build the kernel with
Rust support. This sometimes needs to be obtained by hand when using a
standalone version of 'rustc' not managed by 'rustup'. Currently, the
documentation suggests cloning the 'rust' repository to obtain these
sources, but this is quite slow (on the order of a multiple minutes).
Change this documentation to suggest using the source tarball instead.
The tarball includes only needed files (<5M) and is significantly faster
to download; this is more in line with what 'rustup' does.
Also simplify wording of the relevant section.

If @out_iov and @out_buftype are passed, then return compounded
responses regardless whether the request failed or not. This will be
useful for detecting reparse points on SMB2_CREATE responses as
specified in MS-SMB2 2.2.14.
No functional changes.

Instead of passing @adjust_tz and some reparse point related fields as
parameters in ->query_path_info() and
{smb311_posix,cifs}_info_to_fattr() calls, move them to
cifs_open_info_data structure as they can be easily accessed through
@data.

With current implementation, when a nested DFS link is found during
mount(2), the client follows the referral and then try to connect to
all of its targets. If all targets failed, the client bails out
rather than retrying remaining targets from previous referral.
Fix this by stacking all referrals and targets so the client can retry
remaining targets from previous referrals in case all targets of
current referral have failed.
Thanks to samba, this can be easily tested like below
* Run the following under dfs folder in samba server
$ ln -s "msdfs:srv\\bad-share" link1
$ ln -s "msdfs:srv\\dfs\\link1,srv\\good-share" link0
* Before patch
$ mount.cifs //srv/dfs/link0 /mnt -o ...
mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)...
* After patch
$ mount.cifs //srv/dfs/link0 /mnt -o ...
# ls /mnt

Both `core` and `alloc` have their `cfgs` (such as `no_rc`) missing
in `rust-project.json`.
To remedy this, pass the flags to `generate_rust_analyzer.py` for
them to be added to a dictionary where each key corresponds to
a crate and each value to a list of `cfg`s. The dictionary is then
used to pass the `cfg`s to each crate in the generated file (for
`core` and `alloc` only).

If an fsverity builtin signature is given for a file but the
".fs-verity" keyring is empty, there's no real reason to run the PKCS#7
parser. Skip this to avoid the PKCS#7 attack surface when builtin
signature support is configured into the kernel but is not being used.
This is a hardening improvement, not a fix per se, but I've added
Fixes and Cc stable to get it out to more users.

1. XGMAC Core does not have hash_filter definition, it uses
vlhash(VLAN Hash Filtering) instead, skip hash_filter when XGMAC.
2. Show exact size of Hash Table instead of raw register value.
3. Show full description of safety features defined by Synopsys Databook.
4. When safety feature is configured with no parity, or ECC only,
keep FSM Parity Checking disabled.

====================
ipv6: update route when delete source address
Currently, when remove an address, the IPv6 route will not remove the
prefer source address when the address is bond to other device. Fix this
issue and add related tests as Ido and David suggested.

Add a test case for IPv6 source address delete.
As David suggested, add tests:
- Single device using src address
- Two devices with the same source address
- VRF with single device using src address
- VRF with two devices using src address
As Ido points out, in IPv6, the preferred source address is looked up in
the same VRF as the first nexthop device. This will give us similar results
to IPv4 if the route is installed in the same VRF as the nexthop device, but
not when the nexthop device is enslaved to a different VRF. So add tests:
- src address and nexthop dev in same VR
- src address and nexthop device in different VRF
The link local address delete logic is different from the global address.
It should only affect the associate device it bonds to. So add tests cases
for link local address testing.
Here is the test result:
IPv6 delete address route tests
Single device using src address
TEST: Prefsrc removed when src address removed on other device [ OK ]
Two devices with the same source address
TEST: Prefsrc not removed when src address exist on other device [ OK ]
TEST: Prefsrc removed when src address removed on all devices [ OK ]
VRF with single device using src address
TEST: Prefsrc removed when src address removed on other device [ OK ]
VRF with two devices using src address
TEST: Prefsrc not removed when src address exist on other device [ OK ]
TEST: Prefsrc removed when src address removed on all devices [ OK ]
src address and nexthop dev in same VRF
TEST: Prefsrc removed from VRF when source address deleted [ OK ]
TEST: Prefsrc in default VRF not removed [ OK ]
TEST: Prefsrc not removed from VRF when source address exist [ OK ]
TEST: Prefsrc in default VRF removed [ OK ]
src address and nexthop device in different VRF
TEST: Prefsrc not removed from VRF when nexthop dev in diff VRF [ OK ]
TEST: Prefsrc not removed in default VRF [ OK ]
TEST: Prefsrc removed from VRF when nexthop dev in diff VRF [ OK ]
TEST: Prefsrc removed in default VRF [ OK ]
Table ID 0
TEST: Prefsrc removed from default VRF when source address deleted [ OK ]
Link local source route
TEST: Prefsrc not removed when delete ll addr from other dev [ OK ]
TEST: Prefsrc removed when delete ll addr [ OK ]
TEST: Prefsrc not removed when delete ll addr from other dev [ OK ]
TEST: Prefsrc removed even ll addr still exist on other dev [ OK ]
Tests passed: 19
Tests failed: 0
